This forum is for Audacity 2.x on Mac OS X 10.4 and later.Please state which version of OS X you are using, the exact three-section version of Audacity from Audacity > About Audacity and whether you obtained the .dmg installer or the zip.

Audacity 1.2.x and 1.3.x are obsolete and no longer supported. If you still have those versions, please upgrade here. The old forums for those versions are now closed, but you can still read the archives of the 1.2.x and 1.3.x forums.

I split this from viewtopic.php?f=47&t=64676&p=175823 (the topic you posted to). Even if the problem appears the same to you, it is best to start a new topic. Your crash report is not the same as that of the user in the other topic.

Can you please say exactly how you are launching Audacity. Was it quit before and you are executing the Audacity icon in the Dock, or are you using File > New after having closed Audacity with the red button? Are you dragging in or opening a file in Audacity once the program is open, for example by using a menu command? If so, which menu command are you using?
